my buddy is looking at buying a 2004 LB7 duramax with 50,000 miles on it. one of our techs said to stay away from it. he wants to know if thats the case. they just replaced the injectors. is this a good engine?

um yeah from what i have heard the lb7 is an awesome engine other than the injector problems that they had but yeah tell him to go for it:U:

I would definitely go for it with those low miles. :U: If the injectors have just been replaced thats even better plus theres the extended injector warranty to 200,000miles. I love mine, they're supposed to be the easiest to get good mileage with. Other than injectors theres no real problems that i have heard of.

right on thank you guys

:c:

anytime! :5:

Other thatn the injector thing, they are solid engines/drivtrains. Since the injectors have already been replaced, that's a bonus. :U:

I have 3 LB7's in my fleet, one with 210k, one with 185k and one with 170k. Other than the injectors, they've all been trouble free. :5:

I just picked up a 2003 GMC dmax LB7 and hasnt had an injecter prob yet with 85,000miles, my unlce has a 2001 with 230,000miles and replaced injecters on his and a wheel bearing thats it, these trucks are great and the motors are awesome. He replaced his injecters with 2006 injecters i belive. If i have to replace mine thats what i think i will do put 2006 injecters in it.. But if i was him I would get the truck it sounds like a real nice one.

I think they are great, I wish I still had my LB7. Other then what is mentioned in this thread I would say they are great.

well the great thing about the thing that went wrong (the injecters) there a relitivly easy fix.
